Terminals - Ring Connectors

51989-1 terminals, also known as ring-type terminals, are widely used in many different electronic products. Developed by the International Electrotechnical Commission (IEC), they are designed for connecting wires to circuit boards, and support a wide variety of wire sizes and types. Because of their reliable performance and wide availability, 51989-1 terminals are commonly used in a variety of electrical and electronic systems, including aerospace, industrial, automotive, and consumer products.

Applications of 51989-1 Terminals

51989-1 terminals are well suited for connecting various types of wires. They are mainly used in applications requiring frequent connection and disconnection of wires such as motor starters, panel switches, and safety assemblies. In addition, they are also commonly used for premise wiring, signal transfer, and power distribution.

Working Principle of 51989-1 Terminals

The 51989-1 terminal is based on a crimping system, meaning that the terminal is inserted into the contact body and crimped onto the wires. This requires special tools and techniques. Additionally, due to the high contact forces generated by this system, the variations in both contact and wireMaterial are minimized and the connection is highly reliable.

When the terminal is crimped onto the wires, it creates a mechanical connection between the terminal and conductors. This mechanical connection creates a low resistance electrical path that ensures a reliable connection. Additionally, the inner sleeve of the terminal provides a physical support to the wires and prevents them from detaching.

Conclusion

In conclusion, 51989-1 terminals are widely used in a variety of electrical and electronic systems due to their reliable performance and wide availability. They are based on a crimping system which creates a highly reliable electrical path between the terminal and conductors. As a result, 51989-1 terminals are well suited for a variety of applications, including motor starters, panel switches, safety assemblies, premise wiring, and more.
